the models that needed a diffusers this install did not have (v0.5.11)

Krea-2-Turbo and LTX-2.5 have sat disabled with the same note: the classes
they name -- Krea2Pipeline, LTX2DurationHead, LTX2VideoDiffusionDecoderModel
-- did not exist in diffusers 0.38. They are in 0.42.1, a release rather than
git main, so the floor moves.

The pin that matters is the one next to it. diffusers 0.42 wants
huggingface_hub >=1.32, transformers 5.x refuses >=2.0, and pip resolves 2.3.0
given the chance -- which leaves transformers unimportable and every model
with it. The usable window is 1.33 and it is written down here rather than
rediscovered.
